Madagascar is an extremely diverse and geographically complex area boasting levels of endemism that blatantly raise questions about their origins. There is evidence that these endemics arose via insitu diversification during Madagascar's about 88 million year isolation, even though it was essentially in the middle of Gondwana with ample opportunity to acquire inhabitants. Madagascar's high levels of diversity and endemism make it an ideal location to study speciation, especially considering the evidence that such high levels speciation occurred in Madagascar itself. Several hypotheses have been formulated to relate the complex geography to genetic divergence, and thereby speciation. I explore three hypotheses concerning the effect of mountains, rivers, and watersheds on the genetic distribution of the endemic Malagasy ant species Odontomachus coquereli . I recovered three genetic clusters from STRUCTURE arranged from north to south. Genetic diversity in these clusters decreases southward, suggesting a southward migration. Divergence time analysis in IMa2 indicates that these clusters were formed by splits during the last two consecutive ice ages, and the geographical positioning of these clusters indicates that these splits coinciding with ice ages were aided by different montane refugia within the species. Together, the data show that climate change and refugia have been the driving force of genetic structuration in this species.

Across the Afrotropical and Malagasy regions, ants are one of the most conspicuous and ecologically dominant animal groups. From driver ants to weaver ants, there are over 2,000 species in Africa alone and over 600 in Madagascar. Ê Ants of Africa and Madagascar introduces readers to the fascinating and diverse ant fauna of the Afrotropical and Malagasy regions. Featuring illustrated keys to subfamilies, separate keys to Afrotropical and Malagasy ant genera, and distribution maps, it also describes diagnostic characters, explores ant ecology and natural history, and includes a list of all currently recognized ant species in the regions. This detailed guide is an essential tool for entomologists and myrmecologists working with and learning about this diverse population of Formicidae.

"In this enormously useful book, a profound need is met by a profound contribution, the first such comprehensive work in over fifty years. While brief, Ants of North America is the distillation of a vast amount of study and practice. It is a joy to browse and read, and will have an important impact on the study of ants."—Edward O. Wilson, University Research Professor Emeritus, Harvard University "Two of the most prolific ant faunists have produced a marvelous taxonomic guide to the ant genera of North America. The keys and genus descriptions are succinct and easy to read, the illustrations superb. This book is a must for entomologists, ecologists, and particularly all who study ants."—Bert Hölldobler, Foundation Professor of Life Sciences, Arizona State University "This book represents a bold advance in the study of North American ants. It provides, for the first time, an accessible and lavishly illustrated guide to all the ant genera occurring in the United States and Canada. It will greatly enhance both public interest in ants and scientific investigation of their ecology, behavior and evolution."—Philip S. Ward, Department of Entomology and Center for Population Biology, University of California at Davis

This is the only comprehensive account of all eight species in the genus Adansonia. It describes the historical background from the late Roman period to the present. It covers the extraordinary variety of economic uses of baobabs. There are also appendices on vernacular names, gazetteer, economics, nutrition and forest mensuration. This book fills a gap in the botanical literature. It deals with a genus that has fascinated and intrigued scientists and lay persons for centuries.

The book integrates our understanding of the factors and processes underlying the evolution of multicellularity by providing several complementary perspectives (both theoretical and experimental) and using examples from various lineages in which multicellularity evolved. Recent years marked an increased interest in understanding how and why these transitions occurred, and data from various fields are providing new insights into the forces driving the several independent transitions to multicellular life as well as into the genetic and molecular basis for the evolution of this phenotype. The ultimate goal of this book is to facilitate the identification of general and unifying principles and mechanisms.

The incredible global diversity of ants, and their important ecological roles, mean that we cannot ignore the significance of ants in ecological systems. Ant Ecology takes the reader on a journey of discovery from the beginnings of ants many hundreds of thousands of years ago, through to the makings of present day distributions.
